Abstract
The present invention relates to a test plant (10) for digital mobile radio systems comprising one or more radio base stations (RBSs) (12), a corresponding base station controller (BSC) (11) and a testing apparatus (14) interposed between the RBSs (12) and the BSC (11). The test plant (10), and the testing apparatus (14) in particular, make it possible to check mobile radio system performance while allowing proprietary Operation & Maintenance messages to travel transparently between the RBSs (12) and The BSC (11), and generating, in the apparatus (14), radio protocol messages (Radio signaling Link messages) which in general constitute the portion of information on which testing is carried out and are organized in accordance with predetermined standards. Thanks to the technique described, the testing apparatus (14) can be used in proprietary configuration belonging to any vendor or mobile radio systems without having to be specialized on a case by case basis in order to manage Operation & Maintenance messages, as is the case with prior art systems.
